• forms a protective barrier around the cell
• permeable
• outer living surface of any cell

• contains nutrients required by cell to carry out life processes
• jelly-like substance which supports organelles

Nucleus

(Chromatin)

(Nucleolus)

The nucleus controls all activities in the cell. It is contains the code(DNA) to make proteins.

Chromatins: granular; become chromosomes during cell division
Nucleolus: small dense area in nucleus

• Storage areas
• store water in plant cells
• plant cells usually have one big vacuole, animal cells have lots of little ones
• often transparent

• where sugar is converted into energy through cellular respiration (glucose + oxygen> carbon dioxide + water + energy)
• sausage shaped

• break down invading bacteria
• if cells are not workeing properly they will release lysosomes in order to commit suicide
• contain enzymes to break things down at the cellular level

• takes what was made at the ribosomes (polypeptides) and modify/add another polypeptide if needed
• looks like a stack of plates

• makes proteins
• look like tunnels through the cytoplasm
• transport proteins through cytoplasm
• have ribosomes attached

• where proteins(AKA polypeptides) are assembled
• chains of amino acids become proteins
• VERY VERY tiny-- measured in nano metres (10^-9m)

• responsible for production of fats/oils
• transport stuff
• no ribosomes attached

• maintains cell's shape
• made up of lots of tiny proteins called microfilaments
• helps cell move

• present only in plant cells
• rigid frame around cell which provides strength and support
• not living
• plant cell has one so that the vacuole does not explode- it is contained

• contains chlorophyll(which performs photosynthesis)
• has coinlike stacks of grannum (each coin part is called a thylakoid)
• big enough to see with compound light microscope
